Hey, this is a good follow up by you all. The pictures are great, and thanks for the name. But still, the color descriptions are too vague to identify these venomous snakes. "Grey, tan and yellow" could be any snake. I'm hoping to find something more clear and precise.

The snake I saw looked like a viper, but half of it was some weird, motley color and the other half criss-crossed black and red. Now what the heck kind of snake was this?

Korea is relatively unexplored by biologists and environmentalists. Koreans themselves by and large appear to have little widespread knowledge of their own natural heritage. I found various sites that state Korea has between 20 and 29 species of reptile: but none could be sure, or name them individually.

You may need a guide to reptiles of China or Japan, to have a chance of covering the Korean peninsula.

Currently James is working on a field guide to Korean wildlife. It will be the first of its kind to be published in the English language. This handbook will cover Korean natural history, ecology, and wildlife identification. It is written for the travelers that explore Korea's mountains, rivers and valleys and want to learn more about what flora and fauna exist on the Korean peninsula. Chapters include commonly encountered mammals, reptiles and amphibians, along with animals that are endangered and facing extinction.

Is there some venemous snake that hangs around in bamboo forests, and is green like bamboo leaves? I'm ok with snakes on the ground but hanging around in trees?
Speaking of reptiles I saw what the kids say is a 'silk frog'. It has lime green back with black dots. While its stomach is red/orange with black dots. Good lookin' frog.
